About this programme

This project reviewed previous attempts to provide a verification method for clause E3 of the New Zealand Building Code. It compared these with alternatives, such as computer simulations or prescriptive requirements. This laid the platform for further work in the Warmer, Drier and Healthier Buildings research programme, which aims to establish a verification method for clause E3. The project also involved collaboration to ascertain an implementation pathway. It reviewed how verification methods and acceptable solutions have been developed in the past. The aim was to produce a smoother, more targeted approach to these.
